Senate Advances Nuclear Investment Legislation
March 24, 2026
The U.S. Senate, led by Senators Jim Risch and Ruben Gallego, has introduced the Accelerating Reliable Capacity (ARC) Act to establish a risk reduction program aimed at accelerating investment in new commercial nuclear reactors. This bipartisan legislation supports the Department of Energy's initiatives to enhance U.S. energy security by reducing financial risks associated with advanced nuclear projects, including cost overruns and commercialization challenges. The ARC Act offers enhanced financing terms and limited federal cost sharing to promote deployment of advanced nuclear technologies, reinforcing U.S. leadership in nuclear energy amid growing domestic energy demands and global competition.
- The ARC Act creates a federal risk reduction program to mitigate unforeseen costs for first-of-a-kind nuclear projects, facilitating earlier project starts and private sector investment.
- Procurement professionals should anticipate increased contracting opportunities related to advanced nuclear reactor construction and associated infrastructure, particularly in western states such as Arizona, Idaho, Montana, Utah, and Wyoming.
- Vendors specializing in small modular reactors (SMRs) and advanced nuclear technologies, like Holtec International, may benefit from expanded federal support and financing incentives.
- Energy sector contractors and utilities should evaluate how this legislation impacts project financing, risk management, and partnership opportunities with federal agencies like the Department of Energy and national laboratories such as Idaho National Laboratory.
Providing targeted cost overrun protection for first-of-a-kind projects will help accelerate commercial deployment, meet the significant growth in demand for reliable power that our industrial sector and economic competitiveness require, and ensure continued U.S. leadership in nuclear energy.
— John Wagner
Federal incentives have a critical role to play in bringing new nuclear technology to market. The ARC Act represents a pivotal step of moving projects from studies and speculation to shovels in the ground and unlocking meaningful private sector investment.
— Kenneth Cooper, International President of IBEW
The ARC Act is a timely and strategically important step toward strengthening Americaβs national and energy security. By addressing key financing challenges that have slowed deployment of advanced nuclear technologies, this legislation will help ensure the United States can build the reliable, resilient energy infrastructure needed to power our economy, support critical defense missions, and compete globally.
